CENTRIFUGAL MACHINE.

SPECIFICATION forming part of Letters Patent No. 559,059, dated April28, 1896. Application filed September 16, 1895. Serial No. 562,709. (Nomodel.)

T0 at whom it may concern,-

Be it known that I, ADAM I-IEBERER, a citizen of the United States,residing in the city of Alameda, county of Alameda, and State ofCalifornia, have invented certain new and and for the separation ofliquids and solid matter and substances from each other in the variousarts and manufactures.

The present improvements comprise a cylindrical separator mounted forrotation upon a horizontal axis and means combined therewith for tiltingit at an angle to facilitate the removal of the solid matter orsubstances re maining at the end of its operation, and means forcarrying away the liquid extracted during the operation, together withother parts and details of construction producing a simple, efi'ectiveand rapidly-operating machine, as hereinafter more fully described, andpointed out in the claims.

The nature of the said improvements and the manner in which I proceed toconstruct a centrifugal machine for sugar-works in accordance therewithare fully explained and set forth in the following description,reference being had therein to the accompanying drawings, forming partof this specification.

Figure 1 is a side elevation of the machine, with the cylinder and partsof the framework shown in longitudinal section. Fig. 2 is a side View ofthe portion of the conductingpipe through which the solution to beoperated on is conveyed from the supply-tank into the cylinder, theinterlocking ends of the two sections of pipe forming this conductorbeing here shown in top view. Fig. 2 is a side view in detail showingthe construction of that section of the conducting-pipe which isattached to the cylinder. Fig. 3 is a front elevation of the machine,taken from the left hand of Fig. 1. Fig. 4 is a rear elevation takenfrom the right hand of Fig. 1.

A A are the upright timbers, and B B horizontal timbers, of a suitablestiff frame to carry and support the working .parts.

0 indicates a circular frame or carriage, formed. of two flat rings 0fastened together at proper distance apart, and (J O are blocks I plates03 at regular distances apart around the circle, and E is thecentrifugal cylinder of which this frame or carriage is the princi-' palsupport.

Two of the flanged wheels D are placed below and two above the line ofthe trunnions,

and on these four wheels the cylinder is rotated by means of powerapplied at one end of the cylinder. The position at such time ofoperation is horizontal, but when at rest and during the cleaning outthe cylinder is tilted by elevating one end. At such time the trunnionsc of the swinging frame orcarriage form the center, the parts being sobalanced and arranged that the cylinder swings readily on the center.

E is a circular rail extending around the body of the cylinder andfastened to the outer surface to form a track for the wheels. The

head or bearing portion of the rail is cylindrical'in cross-section, andthe rims of the wheels between the fian ges are of corresponding shapeto set over the rail, by which means the cylinder is confined in placein the frame or carriage and is kept from slipping through the openingwhen tilted at an angle.

The body of the cylinder is constructed of an outer closednon-perforated shell 1 and an inner shell 2,with perforations orapertures 3 3 all aroundthe circumference. The two shells set one insidethe other and are of different diameters, leaving an annular space 4between the two shells. The ends of the cylinder are formed of flangedrims or heads, of which one is a closed head 5, having a centralaperture 6 for a hollow shaft F, and the other is a ring 7, with aflange 7% Thus the cylinder is open to the outside at one end, but isclosed at the other end, and the annular space is closed at both ends bythe flanges or parts of the rims that set between the two shells. Therim at the closed end stands outward beyond the body of the cylinder andhas pas sages 8 8, that run toward the center and thence longitudinallythrough the flange and open into the annular space. These passages formoutlets for the liquid from the space 4 through the head to the outside,and the same are arranged at proper intervals apart all around thecircumference.

G is a circular trough that surrounds and covers this rim of thecylinder-head to catch and carry away the liquid as it is dischargedfrom the annular space through the passages before mentioned, and H Hare conductors leading from below the trough to any distant point andconnected with the trough by suitable couplings or means that allow thetrough to belifted with the cylinder as that end is raised and to belowered into position when the cylinder is brought back to place in theframe. The construction and arrangement of this trough is well shown inFigs. 1 and 3 of the drawings. The general form of the trough iscircular, but at the bottom it has a rectangular shape with a flatbottom 9, and the top and ends of this rectangular portion G are closedin. There are outlets in the bottom with surrounding rims or tubes 12,that extend downward and fit closely into the upper ends of theconductors H on the frame,

pendicular sides being made shorter than the other side, as shown inFig.1, its edge g will clear the rim of the cylinder-head and allow thetrough to be taken off the cylinder when it is necessary to reach theoutlet-passages. The opposite end of the cylinder is closed in aroundthe margin by a removable plate or cover I, having an open center and aflanged rim with locking-lugs 14, shaped to fit over and engage the rimof the cylinder-head, the rim being slotted, as shown at 13, Fig. 3, tolet in the lugs behind the rim. When this cover is in place, the lugsare caused to engage the back of the rim, as shown in Fig. 1, byrotating the cover. readily placing and taking off the cover it isprovided with handles I I The hollow shaft E is fixed in thecylinderhead, and extending inwardly nearly the entire length of thecylinder it is connected at the outer end with a feed-pipe orsupply-pipe, by means of which the solution to be operated on is fedinto the cylinder. The shaft is perforated with holes f and its innerend is closed by a cap F. Power is applied to the part of the shaftoutside in any suitable manner to rotate the cylinder. Usually this isdone by means of gearing, and in the present construction thecylinder-shaft is connected by friction-gears 15 16 with a driven shaftK.

mounted on the stationaryframework.

For'this purpose and for The manner of connecting the hollow shaft toand disconnecting it from the supply-pipe L will be understood byreferring to Figs. 1, 2, and 2.

The stationary pipe L is connected with the outlet of a supply-tank X,and is provided with a gate L for regulating the fiow of the solutioninto the cylinder.

M is a flanged head on the outer end of the pipe L, and N is a head ofcorresponding form on the adjacent end of the hollow shaft, the faces ofthese two parts being fitted to form a close joint when broughttogether, being also finished with interlocking couplings that draw themtogether and produce a tight joint.

The form of coupling which I prefer to use is composed of the hooks 1717 on the end of one part and the inclines or wedge-shaped faces 18 1-8on the sides of the other part. This coupling is separated when thecylinder is tilted from that end, and is brought together and a tightjoint formed when the cylinder is brought down again to the horizontalposition.

In order to permit rotation of the hollow shaft, that portion betweenthe driving-gears and the coupling before mentioned has a telescopicjoint 19, one part of which carries the coupling on the outer end and isfitted to the end of the main portion of the shaft in suitable manner tosecure a tight joint and at the same time allow the moving part to turnfreely on the stationary part.

P is a bearing-block supporting the shaft L, and R R are fixedguide-rails between which the bearing-block is confined, and is fittedto slide up and down. The guide-rails are bent to a quadrant shape, withthe outer edges struck from a center at the trunnions O and a rack R isformed on each rail to engage pinions S S, mounted on the bearingblockP. The shaft 22 carrying the pinion is furnished with a long bearing 25in a bracket Eton the top of the block P, and a hand-wheel T is madefast on one end of the pinion-shaft for working the pinions. These partsform a simple and efficient means of moving the bearing-block in thefixed-quadrant to raise and lower the back end of the cylinder in theframe.

The joint on the hollow shaft is situated in the bearing-block, and thepart L is prevented from turning accidentally, whenever thebearing-block is raised and the parts of the coupling are separated, byproviding lugs 23 23 or projections on the sides of the section of pipeand on the face of the bearing-block. A limited extent of longitudinalmovement of this section at the joint 19 allows the faces of thecouplings to be drawn up by the inclines and hooks, and thus secures atight joint.

The machine thus constructed is especially adapted for sugar-works, butit can be used as well for separating liquid from solid mat ter andsubstances in other arts and manufac'tures where pressure is notrequired.
